C: CAUTION
• Wear appropriate work clothing, including a cap, protective goggles and protective shoes when performing
any work.
• Remove contamination including dirt and corrosion before removal, installation or disassembly.
• Keep the disassembled parts in order and protect them from dust and dirt.
• Do not place the oil pan with its inner side facing up until it is installed, to prevent intrusion of foreign matter
into the control valve body.
• Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, disassembly and replacement.
• When disassembling the case and other light alloy parts, use a plastic hammer to force it apart. Do not pry
apart with screwdrivers or other tools.
• Vehicle components are extremely hot after driving. Be wary of receiving burns from heated parts.
• Use SUBARU genuine CVTF and recommended grease. Do not mix CVTF, grease etc. of different grades
or manufacturers.
• Be sure to tighten bolts and nuts to the specified torque.
• Place lifts, shop jacks or rigid racks at specified locations.
• Apply CVTF onto sliding or revolving surfaces before installation.
• Apply CVTF onto the press-fitting surface of the part before press-fitting the part using a press.
• Replace deformed or damaged snap rings with new parts.
• Before installing O-rings or oil seals, apply sufficient amount of CVTF to avoid damage and deformation.
• Be careful not to incorrectly install or fail to install O-rings, snap rings and other such parts.
• Before securing a part on a vise, place cushioning material such as wood blocks, aluminum plate, or cloth
between the part and the vise.
• Avoid damaging the mating surface of the case.
• Before applying liquid gasket, completely remove the old liquid gasket.
• After removing the sensors, breather hose and plugs, plug the holes to avoid foreign materials intruding as
necessary.
• During disassembly or assembly, be sure to use nylon gloves or paper towels. Do not use cloth gloves or
waste cloth.
